**Question 1 from 10: What is the oldest mathematical object?**

The history of mathematics aims to investigate the origin of mathematical discoveries before the modern period, when mathematical knowledge spreads around the world. The study and development of mathematics took place in various areas of the world. Mathematicians from ancient Greece have contributed by refining mathematical methods, in particular by introducing deductive reasoning and mathematical rigor in demonstrations, expanding the subject of mathematics. Chinese mathematicians have contributed to writing in a numerical system, those in Indian-Arabic space have introduced the rules of use of operations as we use them today that evolved over the first millennium in India and was transmitted in the West through Islamic mathematicians, who in turn developed and expanded the mathematics known until then.
